These ships were designed to increase control during monsoon season with the innovation of cotton sails. The development of ships increased trade in the Indian Ocean. Another technology that helped with trade in the Indian Ocean was the magnetic compass innovated in China. The compass helped sailors keep track of their location.

mentioned previously being planted more than half a century earlier. Though not a modification in the modern sense, strains like the weather resistant grain were created through a process with an identical end result known as selective breeding. Selective breeding is the cross pollination of plants with more desirable traits to create improved versions of those plants. It was practiced unintentionally thousands of years ago, due to a lack of understanding of the genome. However, it was soon…

National Park (www.nps.gov/ever). Now, since the pythons first made travel into the area in 1979, they have found the perfect breeding and feeding grounds and their numbers have grown to at least 300,000 snakes.

A common fruit fly, Drosophila melanogaster, was used in the experiment to determine the mode of inheritance of the apterous mutant flies over several generations. The possible modes of inheritance could have been autosomal or X-linked and dominant or recessive. It was predicated that the apterous Drosophila flies were autosomal recessive, hence evaluated using reciprocal monohybrid crosses. The F1 and F2 generations were observed and compared to the hypothesis. An analysis of the F2 generation…
